Works on sectional door that roll up, rather than doors that flip up.
Another compact device that comes in handy for kids, family or yourself to have is the mini remote, is a simple solution to have an easy access to your home without using keys. Instead of using bulky keys or carrying your keys from a long walk, jogging, etc. go keyless with the mini remote device, which will give you a faster way to access to your home. It's compatible with all major brands of garage door openers, and allows control of two garage doors or home lighting through a safe and secure connection. It measures 2.25" x 1.25", and has a durable design of a lightweight, slim feature. What I like is its lightweight, doesn't weigh down on your hands, pocket, jacket, etc. and it's convenient for the whole family to use. The mini remote is available for $49.99 at Home Depot in the US and Canada. Chamberlain has high quality products which you can find at http://www.chamberlain.com/
